MMIC AMPLIFIER
Product Description
The SGA5589Z is a high performance SiGe HBT MMIC Amplifier. A Darling-
ton configuration featuring one-micron emitters provides high F
T
and
excellent thermal performance. The heterojunction increases breakdown
voltage and minimizes leakage current between junctions. Cancellation of
emitter junction non-linearities results in higher suppression of intermodu-
lation products. Only two DC-blocking capacitors, a bias resistor, and an
optional RF choke are required for operation.

Description
RF input pin. This pin requires the use of an external DC-blocking capacitor chosen for the frequency of operation.
Connection to ground. Use via holes for best performance to reduce lead inductance as close to ground leads as possi-
ble.
RF output and bias pin. DC voltage is present on this pin, therefore a DC blocking capacitor is necessary for proper oper-
ation.

Evaluation Board Layout
Mounting Instructions:
1. Solder the copper pad on the backside of the device package to the ground plane.
2. Use a large ground pad area with many plated through-holes as shown.
3. We recommend 1 or 2 ounce copper. Measurements for this data sheet were made on a 31mil thick FR-4 board with 1
ounce copper on both sides.
